I'm pretty sure we do visa sponsorships, but I'll have to check. Re: remote work, we have a fun office culture and like to talk face-to-face as much as possible. That said, we do have some people that work from home periodically, but we don't hire full-time remote workers.
The salary depends on whether you're in San Francisco or Birmingham, as well as which position you get and your experience level. I'm not 100% sure what the salary bands are, per se, but I'm happy with my compensation, and I think you would be too.
Hello. At this time we do not have the resources to commit to this. With the current political climate it is even more challenging than it has been in the past. Perhaps the tide will change in 2020 - that is certainly my hope.
